1888 Morgan Silver Dollar. Proof-62 (NGC). The scarcity and popularity of Proof Morgan dollars as a group will certainly result in keen bidder interest in this more affordable 1888. It is a lightly toned specimen with iridescent highlights that appear to drift toward the borders. Well struck for the issue with only a touch of the characteristic softness to the central high points. PCGS# 7323. NGC ID: 27ZH.
